Frankly, if they
were really just in it for the money, I for one would personally be
thrilled to highball the amount Trump & all of his cronies expect to
make from their years in office, multiply it by ten, and give it to
them in straight, no-strings, untaxed cash, if they would resign &
let the winner of the popular vote take office in January. The Republic
would be vastly better off.

On the other hand... Corruption gets to a lot of people who don't care
about (or are even on the other side of) other issues. Clinton lost so
narrowly that any of dozens of factors can be blamed, but among the
leading causes is clearly the (largely false) idea that she was corrupt
(laughable compared to her opponent, of course). And Trump's farcical
claim that he would "drain the swamp" was, apparently, a big deal for
those who voted for him. Certainly the notion that corrupt elites run
things helped him, so that showing that he is the most corrupt of them
will probably do some good with at least some Trump voters.

So... yeah. Trump: corrupt. Let's make that point, early and often, along with all the others.

Update: This quite seriously understates the danger of Trump's corruption. See this Matt Yglesias post for what I missed.
